Twist drill bit KWB 512812 1.2 cm diameter 1 pc
The KWB 512812 twist drill bit has a 1.2 cm diameter and is manufactured from chromium-vanadium (CrV) steel. It is an extra-long, industrial-quality bit with a single spiral and a center point plus two cutting wings, designed to produce accurate, break-out free holes in beams and workpieces when drilling soft and hardwoods.
This drill bit's extra-long design and accurately formed cutting geometry provide controlled, precise drilling in deep or hard-to-reach areas. The CrV steel construction ensures durability and resistance to wear, while the chemical black finish helps reduce friction. The center point and two cutting wings minimize splintering and deliver clean hole exits in timber.
Secure the twist drill bit in a compatible drill chuck ensuring a firm grip. Mark the drilling position on the timber and start drilling at low speed to engage the centre point, then increase speed steadily while applying even pressure. For deep holes, periodically withdraw the bit to clear chips and prevent overheating. Use appropriate drill speed and feed for the wood type to maintain clean holes and prolong bit life.
Use the KWB 512812 for timber drilling applications where clean, break-out free exits are required; clamp workpieces securely, use protective equipment, and match drill speed to the wood species. Avoid excessive side load and overheat to maintain cutting performance and durability.
